To a whom zit mat concern;

. This-burner, 'WlliOh is also'a carhureter; comprises 't'w'o tubular parts "1', which are prefer- ?ably enlarged at their inner ends and arranged to telescope one Withinthe other-{as clearlyv shown in Figs: '1 and 3-; the enlarge --1nents being providedwithperforations; as at 1'1, "for 1 the escape of the carbureted :a'ir or hydrocarbon 'mixturethat it 'mayhe burned in'the' space between'theburner and'the shell f:- Th8j. l3W0" tubular portions of the burner 2 ?pass,;resp'eotively, through the 1 bridges of the caps h and =.cor'nrnunicate-,- respectively with needlervalves m, by. which the supply pfair and hydrocarbon, respectively, to the burner is regulated. Each needle-valve may be threaded into the corresponding cap h, as shown.

For the purpose of regulating the escape of the dead gases from the interior of the shellf or the admission of air thereto a device of an ordinary character may be employed, as shown in Figs. 1 and 3, comprising an inner perforated plate n and an outer perforated plate 0, revoluble upon the inner plate.

If desired, an electric igniter may be provided for the'purpose of igniting the gas from the burner within the shell f, such igniter comprising, as usual, two electrodes p and g, which may be suitably mounted in one of the caps 7t.

In assembling the improved igniter and carbureter the shellf is first placed within the ch amber of the casting a, the filling-piece g is put in place, and the ends of the shell f are engaged with the caps h, in each of which has been placed a corresponding member of the burner and carbureter, secured to the corresponding needle-valve, so that the enlarged ends of the latter shall telescope, as shown in Figs. 1 and 3. The parts of the burner are so related as to make proper allowance for expansion of the burner when heated. The plates & are then applied and are held together by setting up the bolts 70, thereby pressing the caps h firmly against the ends of the shellf and against their seats on the casting and filling-piece, respectively, and holding the latter tightly in its seat. The needlevalves can then be secured to the caps as usual. Should any part of the device be required to be renewed or repaired, it will be obvious that all of the parts can be separated by simply removing the bolts Ya.

In the use of the device in the application thereof illustrated in the drawings the hydrocarbon mixture formed within the burnertubes Z and issuing from the burner-holes Z is ignited, and burning with an intense flame the shell f is quickly heated to the te1nperature required for ignition of the charge which is delivered through the valve-port d upon the globular portion of the shell and is immediately vaporized thereby and ignited. The pressure within the working cylinder, as will be observed, is external to the igniter-shell, and the products of combustion within the igniter-shell are allowed to escape at either end thereof into the surrounding atmosphere. As the oil is admitted through its burner-tube Z it meets at the extremity of the tube the 0pposing blast of air from the alined air-supply tube and is thereby not only completely vaporized, but, being vaporized, is spread radially, so that the flame of the burning mixture is driven radially from the centrally-located burner against the walls of the shell, thereby bringing the same quickly to an intense heat,

suflicient for the ignition of the charge in contact with the outer surface of the shell. It will further be observed that by the globular enlargement of the shell located within the chamber 1) in front of the inlet (1 for the charge the latter is immediately spread and ignited.

I t will be understood that the form and relation of the several parts of the improved igniter and carbureter may be varied as may be required by the conditions of use of the device without departing from the spirit of the invention.

I claim as my invention 1. An igniter for internal-combustion engines, 860., comprising a shell for external contact with the charge to be ignited and communicating internally with the external air and a carbureter and burner placed withinsaid shell and comprising alined tubular members connected respectively with a hydrocarbon-supply and an air-supply and terminating centrally within said shell and means for spreading radially the burning gases, substantially as described.

2. An igniter for internal-combustion engines, &c.,-'comprising a shell having a globular enlargement for'external contact with the charge to be ignited and communicating internally with the external air, and a carbureter and burner placed within said shell and comprising alined tubular members connected respectively with a hydrocarbon-supply and an air-supply and terminating centrally within said globular enlar ement and means for spreading radially t e burning gases, substantially as described.

3. An igniter for internal-combustion engines, 850., comprising a shell for external contact with the charge to be ignited and communicating internally with the external air and a carbureter and burner placed within said shell and comprising tubular members connected respectively with a'hydrOcarbonsupply and an air-supply and terminating centrally and end to end withinsa'id shell whereby theburninggases are spread radially within the shell, substantially as described.

4. An igniter for internal-combustion engines, &c., comprising a shell having a globular enlargement for external contact with the charge to be ignited and communicating internally with the external air and a carbureter and burner placed within said shell and comprising alined tubular members connected respectively with a hydrocarbon-supply and an air-supply and terminatin centrally and end to end within said globu ar enlargement whereby the burning gases are spread radially withinsaid globular enlargement, substantially as described.

5. An igniter for internal-combustion engines, 850., comprising a shell for external contact with the charge to be ignited and communicating internally with the external air and a carbureter and burner placed within said shell and comprising alined tubular members connected respectively from opposite directions with a hydrocarbon-supply and an air-supply and enlarged and perforated at their opposing ends to form a burnerchamber centrally within said shell, substantially as described.

6. The combination with a cylinder of an internal-combustion engine having a chamber and an inlet for the char e, of an i niter comprising a shell having a globular en argement located within said chamber to spread and ignite the charge admitted through said inlet and communicating internally with the external air and a carbureter and burner placed centrally within saidlshell and provided with means for spreading radially the burning gases, substantially as described.

7. The combination with a cylinder of an internal-combustion engine of an igniter comprising a shell subj ected externally to the pressure within the cylinder and 0 en for communication with the external air, and a h ment located within sai chamber to spread and ignite the charge admitted through said inlet, and communicating internally with the external air and a carbureter and burner placed centrally within said shell, substantially as described.
